To /P or not to /P

Due the small wave length of the uplink and downlink frequencies used by QO-100 NB transponder, it's possible to design very compact Portable stations. Many have taken advantage of this fact and built their own portable station.

As today (19 March 2023) we have 444 Portable stations on our database, about of 7% of the valid station total (6221).

If on the operating side that has been an amazing advantage (creating many opportunities of operations from rare DXCC or Grid Locators), on the "administrative" side portable stations sometimes are a major "headache", simply to know the correct callsign!

Here are the most commons reasons:

Very often we see in our database a call with 90% in one format, and the remaining 10% using something different.

In order to help our members to know what is the right call, we created a list with the most popular calls.

The call most reported on the database (and mostly likely reported by the DX operator) is listed on the first column. The other columns show the alternative formats logged by our members.
